下载 swfupload 文件夹里面包含handlers.js，swfupload.js，swfupload.swf 三个文件。

我的是和ssh项目整合在一起的。因为struts2的拦截器会拦截所有请求，在跳转到上传文件的servlet中时request请求会被转换为struts的请求。所以要去掉struts的请求。

假如web.xml配置的拦截所有请求，可以修改这里，不拦截所有

<filter>        <filter-name>struts2</filter-name>        <filter-class>            org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter        </filter-class>        <init-param>            <param-name>config</param-name>            <param-value>                struts-default.xml,struts-plugin.xml,resources/struts/struts.xml            </param-value>        </init-param>        <init-param>            <param-name>actionPackages</param-name>            <param-value>com.yuncai.modules</param-value>        </init-param>    </filter>    <filter-mapping>        <filter-name>struts2</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>

或者在struts.xml中加上 <constant name="struts.action.excludePattern" value="/servlet/.*" /> struts不会拦截这个路径下的所有

上传文件的servlet的路径
